Main equipment for smelting ferroalloy. Ferroalloy electric furnaces are divided into reduction electric furnaces and refining electric furnaces. There are various types of electric furnace, such as electric furnace with open or semi arc operation, or electric furnace with submerged arc operation. Electric refining furnace is used to refine medium carbon, low carbon and micro carbon ferroalloys.

Traditional ferroalloy submerged arc furnaces generally use pre-baked carbon blocks and wide coarse joints to build the furnace lining, and adjust the primary current to control the depth of the electrode inserted into the furnace (that is, the load of the electric furnace). Take the main equipment of a company's 2*25.5MVA submerged arc furnace as an example. Its lining adopts semi-graphite charcoal brick fine-seam masonry technology, but the redness of the furnace bottom appeared three months after the furnace was opened. Through fine furnace anatomy and cause analysis, find out the solution to the problem.
